Description: Celestion NTR21-5010JD 21" Neodymium 1600 W RMS 8 ohm Speaker Driver Celestion's NTR21-5010JD 21" subwoofer features an advanced neodymium-powered motor for maximum output without maximum weight. To keep control of the driver when used with high power amplifiers (of up to 1,600 watts RMS), Celestion employs double suspension and a multi-roll surround for exceptional linearity during extreme excursion moments that are common with lower frequency reproduction. A lightweight carbon fiber-loaded paper cone is used due to its rigidity and ability to respond quickly to audio impulses. Intelligent heat management is designed into the cast aluminum chassis, high temperature 5" inside/outside wound voice coil, and extensively vented neodymium magnet which prevents thermal compression and the resulting loss and sensitivity. Last, but certainly not least, this 21" subwoofer has an amazing 9 mm of Xmax to move massive amounts of air.
